Closing a Gap Between Front Teeth

Dr Ho provides two different in-house options for closing a gap between the front teeth: a porcelain veneer that covers the front of the tooth, or clear aligner treatment (such as Invisalign) that moves the tooth into a new position, and does not offer metal or ceramic braces as a third route. Which of the two is likely to suit a particular gap depends on what is causing it and what the patient is prepared to commit to afterwards, and that suitability is assessed individually rather than assumed from the size of the gap alone.

Veneers and clear aligner treatment compared for closing a gap

The table below compares porcelain veneer treatment and clear aligner treatment across the factors that typically matter for a patient deciding between them.

What does each option commit you to afterward

Fitting a veneer starts with a step that generally cannot be undone. Once a thin layer of enamel has been taken off the front of a tooth to let the veneer sit flush, that tooth needs a restoration on that surface from then on. A veneer that is damaged, or that reaches the end of its working life, is usually replaced with another veneer, not left as a bare, prepared tooth.

Aligner treatment works the other way around. It does not add anything to the tooth, and there is no equivalent one-off step at the start. The tradeoff sits at the other end of treatment instead. A tooth that has just been moved into a new position is held there mainly by the surrounding gum and ligament tissue, and that tissue settles into the new position more slowly than the tooth itself moved. Until it does, the tooth can drift back toward where it started, which is why a retention plan, commonly a retainer worn on an ongoing basis, typically follows active movement rather than being optional.

In practical terms, a veneer commits a patient to maintaining and eventually replacing a restoration, while aligner treatment commits a patient to a retention routine that protects a result achieved without adding anything to the tooth. Neither commitment suits everyone; which one fits a given patient is part of what an individual assessment covers.

What influences whether a veneer or aligner treatment fits a gap

A gap between two otherwise healthy, reasonably well-aligned front teeth is often the more straightforward case for a veneer, since the change needed is mostly visual and confined to the one tooth. A gap that is part of broader spacing or crowding elsewhere in the mouth is different, because a veneer only changes the tooth it is fitted to and does nothing for the position of the other teeth, while aligner treatment can move several teeth as part of the same course of treatment.

Personal preference plays a real part too. Some patients would rather have a fixed, one-off change than wear an appliance for months; others are comfortable with the daily commitment aligner treatment involves and would rather avoid preparing a tooth that does not otherwise need any work done to it.

Where an assessment shows a gap needs a type of movement that falls outside what either option is designed for, Dr Ho says so and refers the patient to a practitioner who provides that treatment.

Getting an individual assessment

Dr Ho is a registered dentist (DEN0001536037) who examines the gap, the health of the surrounding teeth and gum, and a patient’s preferences before discussing whether a veneer, clear aligner treatment, or another approach may be appropriate. Appointments are available at her office in Mosman Park.

Common questions about closing a gap between front teeth

Can a small gap close on its own without treatment?

Generally not. A gap is held open by the position of the tooth roots and the bone around them, not by extra space that closes up naturally over time, so a small gap in an adult typically stays about the same size unless it is treated.

Does closing a gap with a veneer affect the health of the tooth?

A veneer itself does not treat any structural or gum problem, and the tooth underneath still needs the same decay and gum care as any other tooth. Preparing a tooth for a veneer is a routine part of the treatment, and Dr Ho checks the tooth and surrounding gum before recommending it.
